The calculation of resolution test uses HYRes software, and the
calculation will be done in two parts: vertical resolution and
horizontal resolution.

Digital camera assessment is different from other products. It’s
unlike laptop and DIY which have a lot of software to test
objective data and everything can be seen from the data. However,
assessing the quality of digital camera not only needs certain
objective data, but also needs to combine actual operation and the
shooting proofs. Therefore, our assessment is based on the
principle of objective data and combined rational analysis from the
experienced reviewers to obtain the most objective assessment
results.

ISO 12233 resolution test chart is in accordance with ISO 12233

resolution charts.
